WIREWORKING MACHINE.

Application filed April 14, 1922.

This invention is a wire working machine, the object being to so fashion the wire as to render the same available for use in binding packing boxes and other shipping packages.

In the art pertaining to shipping paclo ages it is desirable to utilize wire a binder; and it is desirable, also, to apply the wire under tension to said packages, and

I while said. binder is under tension to lock together the meeting end portions of the binder, usually by twisting the same. To

apply the wire with facility, a suitable implement required for the performance of the functions of tensioning the wire binder and of locking the same, and to this end the wire is provided adjacent an end portion, or adjacent both end portions, with a shoulder or shoulders whereby in the act of assembling the wire relatively to the package and to the implement, said wire is positioned in a part of the implementfor the shoulder of the wire to co-operate with the implement in a manner to prevent. the wire from slipping when tension .is applied thereto.

The machine of this invention embodies means whereby the wire is deformed to produce a shoulder or shoulders thereon concurrently with the operation of cutting the wire to a length suitable for use 011 shipping packages of a predetermined cross sectional dimension.

In a practical embodiment of the invention, I. employ co-operating swaging dies on an anvil and a plunger for the production of a flattened and shouldered portion on a round wire, the resulting deformation of the wire producing a shoulder adjacent an 40 end portion of the wire. Said dies co-operate to sever the wire adjacent the deformation,

and the cutting operation taking place concurrently with the swaging operation.

It is desirable to produce a plurality of deformations on the same length of wire, one deformation being adjacent one end portion of the out length and the other deformation adjacent the opposite end portion of the same wire length, and to these ends, I provide co-operating dies in multiple on the anvil and the plunger, together with suitable provision on the plunger, for cutting the wire at a point intermediate the multiple swaging dies.

Other functions and advantages of the Serial No. 552,768.

invention will appear from the following description taken inv connection with the drawings, wherein Figure 1 is an elevation of mechanism for cutting a continuous wire into suitable lengths and for producing deformations thereon, said mechanism being shown in connection with an appropriate form of straightening means whereby the wire from a coil is straightened, out to length, and deformed in a continuous operation.

l igure 2 is an enlarged sectional elevation through the (to-acting swaging dies provided on an anvil and a plunger, respective .ly, said dies acting to cut the wire at a point adjacent the; deformation resulting from the swaging action.

Figure 3 is a view in elevation of a cut length of the deformed wire, with a fiattened and shouldered portion adjacent one end, said out length of wire being the product of the operation of the dies il-- lustrated in Figures 1 and 2.

Figure t is a. plan view of the deformed rut length of wire shown in Figure Figure 5 is an elevation, partly in section, of multiple swaging dies and of cooperating cutting dies for producing cut lengths of wire with deformations adjacent the respective ends of the same length of each wire.

Figure 6 is a plan view of the cut length of wire with deformations adjacent its respective ends, the same being the product of the dies shown in Figure 5.

Figure 7 is a View illustrating the action of the multiple swaging dies in producing one cut length of wire with two deformations concurrently with the production of a portion of another out length of deformed wire, with a complete line of severance in termediate the two out lengths.

Figure 8 is a cross section through the deformation produced by the action of the swaging dies, the plane of section being on the line 8-8 of Figure 3.

Figure 9 is a view in side elevation of one form of the machine.

Figure 10 is afront View thereof.

Figure 11 is a detail sectional View of one form of clutch mechanism.

Figure 12 is a detail view of the wire receiving plates.

Figure 13 is a detail of the clutch lever.

As shown in Figures 1 and 2 of the drawings, a plunger A is fitted for vertical reciprocating movement within a suitable guideway 6 provided on a fixed head B, at the bottom of which head is fixedly held an anvil C, the latter being positioned in alinement vertically with said plunger.

D E are the co-operating swaging dies, the die I) being fixedly held on the anvil 13, whereas die E is attached in a suitable manner to the plunger at the lower partthereof, whereby said dies D E are positioned in facing relation one to the other, and the die on the plunger is movable relatively to the die on the anvil. The opposing surfaces of the two dies D E are fashioned to mutually co-operate in swaging a wire round in cross section so as to deform the latter by flattening said wire and producing a shoulder thereon, the wire being indicated at X in Figures 3 and -11, the deformed portion thereof at a and the shoulders at m.

The under face 6 of the movable swaging die E protrudes below the under face of the plunger, see Figures 1 and 2. whereas the upper face {Z of the stationary swaging die D is above the plane of the corresponding face of the anvil C, so that in the downstroke of the plunger and the die E the interval between the faces d e is less than the interval between the plunger and the anvil, whereby dies D E co-operate in acting on the round wire X to compress the metal so as to produce the flattened or deformed part it with the shoulders at," at the ends of the tlatteneifl portion. The flattened portion a ot a width exceeding the diameter of the wire. whereas the thickness of said flattened portion less than the diameter of said wire, as will be understood by refereiue to Figures 3, t and 8.

F is a cuttii'ig die carried by the plunger in a position parallel to the swaging die E and at a desirable distance from the same. The cutting die is fixedly attached to the plunger for vertical movement therewith, and said die 1* is shown. having a cutting edge positioned to shear past the edge f of the anvil, whereby the die F co-operates with anvil C in severing the wire concurrently with the operation of swaging the wire. thus producing at one operation a piece of wire deformed as required and cut to the desired length.

The machine illustrated in Figure 1 is adapted for straightening the wire as itis drawn from a coil. Said machine includes a rotary head G, driven by a pulley and. belt, and equipped with appropriate means, such as the usual rolls, for acting on the wire to straighten the same. The wire from the coil is directed into the guide 72, and advanced or fed at the desired speed by feed rolls ll, between the swaging dies. whence the wire passes into the wire receiving plates 1, operable intermittently as usual for dropping the cut lengths of wire into wire holding receivers or trough which may be said to constitute a bundling mechanism J. all as usual in the art. The motion of the wire receiving plate is timed with the drive shaft (L having the usual eccentric motion for imparting reciprocating movement to the plunger by which the upper swagiug die and. the cutting die are operated.

The shaft (1. by which the plunger A is operated is driven intern'iittcntiy to ellect the reciprocating motion ot upper die E and cutter l but said plunger, die and cutter are normally mined and at rest during the operations of straightening the wire and of feeding a length of wire into a wire receiv- .ing space or socket comprised by romple mental grooves i provided. in the contiguous edges of a pair oi ll()li/,()i'lll2ll plates /1 '1'. ,-onstituting the wire receiving and holding means I. Said plates r" are provided with oblique slots in which are titted studs of supporting arms vi which are rigid with certain of the wire receivers j. and with said slotted platcs is asmcialcd a lever l, the lower end of "hich is provided with a head I; that engages with plates is on the wire receiving plates e" for impzn'ting sliding motion to die latter, whereby the plates are relatively moved so as to open and close by the studs working in die oblique slots o i said plates.

On. shaft a a loose ulley ll, which runs cmuiimiol ly. being driven by a belt (not shown). (Jo-operating with the shaft (.1 and pulley L a clutch M, which is shown as pin slid-ably titted in a groove m ot the shaft. and is received. in a socket m provided in a hub 7 of said pulley L. The clutch pin is impelled by a spring m toward the sockcted part of the pulley, but said clutch pin is held free from engagement with the socket by a clutch lever O, the latter having a wedge member 0 fitting in a groove of the clutch pin. Said clutch lever O is fulcrumed at l on the fixed standard or l cad l5, and to the longer arm o l said lever is attached the trip wire l the latter extending to a. wireoperatcd tripping device designated in its entirety at Q. As usual in the art, the tripping device embodies a slidable rod 9* loosely retained in a groove of one of the receiving plates i, a stop collar 9" lixcdly held on said rod 9, a stop arm fixedly attached to one o I said plate. a" and poslioned in the path of stop collar 9, and a. spring 1 fastened to an upstanding part of the stop collar. The trip wire P is connected to the stop collar or to the trip rod, and when the required length oi straightened wire is fed into position between the plates 2'. ol? the wire holding and receiving means L, then said length of straightened wire imparts movement to the trip rod 9 for pulling on the trip wire 1 and operating the lever O, the wedge of which is rill ill)

Hill

withdrawn. from the notch of the clutch pin, whereupon the spring snaps the clutch pin lengthwise of the shaft and into the socket of huh Z, whereby the pulley drives the shaft (IV for operating the upper die and the upper cutter. This operation of the die and the cutter takes place during a half revolution of shaft (1 and during the remainder ofsaid revolution of shaft a the wedge of the clutch engaa' s with the clutch pin and retracts the clutci from the pulley, leaving the plunger, die and cutter in a raised position, wher a s the driving; rolls It and wire straightener G are in operation c mtinnouf-ily, with the plunger operated quickly and at intervals as detcn'mined by the feed of the wire into the plates 1" of the receiving means i.

The operation is ap iarent. The wire is drawn from the coil and through the straightening head by the feed rolls, and advanced to the required pos tion between the mvaghro dies and mittii'ig dies. whereupoi'i the phmger des aids to bring the swinging; dies together and for the cutting die to shear past the edge of the anvil, as a result of which the wire is cut and deformed at one operation. The plunger :n-iccnds and the wire is fed between the grippers, whereiuimn the plunger again descends for closing the swagzing dies and operating the cutting; dies to swagi'e and cut a length of wire, the grippers being opened to drop the previously out length of wire into the hin'nlhn g device.

The dies of l i rurcs l. and 2 operate as described to produce a single wire cut to a desired length and deformed adjiwent one end portion, as in l-iigures 3-) and at; but it is desirable to produce a wire X cut to a desired length and providi-id with deformations a: 11: adjacent the opposite ends of the same wire X, as shown in liigures 7 and To this end I provide swa 'inp dies in multiple as in Figure 5 and a, cutting die for cutting out a short section of the wire intermediate two of the defornmtions on the lengths X )3, see Figure 7. The multiple swaginu dies are indicated at l) E and. D E provided on the anvil. (l and the plunge A, the movable dies l l l being carried by the plunger, whereas the stationary dies 1.) l) are fixedly held on the anvil. The cooperating dies D E are provided with working; faces (Z 6, as heretofore described, and the other pair of dies, D E, are provided with similar faces 1/ c, the dies 1) E being positioned alongside the dies l) E and suitably spaced with respect thereto. 4

lntern'iediate the movable swaging dies l6 E on the plunger is a single cutting die K provided with two cutting; edges 7c adzpted to cooperate with shear cutting; edges 'm in on the anvil C, and to operate in the space m of said anvil.

In the operation of the double swaging dies and the cut out cutting die of Figure 5, the wire from the coil passes through straightening means and between the dies when the upper dies are raised with respect to the lover dies, but on the descent of the plunger A the dies 1) E produce a deformation and the dies D E produce a second deformation, whereas the cutter K is operated for its edges 7: 70 to shear past the edges m m for cutting out a relatively short section of the wire as at. 0 in Figure 7, whereby the lengths X f are swaged at a, and the wire is cut out at 0 at one operation, as a result of which each length of wire i" formed at successhJe operations with two deformations ll. a see liigures 'T and b, one near each end, and said wire cut into pieces of appropriate length Ii )3.
